what is the change in momentum of a car weighing 1500 kg when its speed increases from 36 km/h to 72 km/h uniformly?plz do not skip any step show all the step clearly.

the formula of change in momentum= mv - mu, where m=mass i.e 1500kg, v=final velocity i.e 72 km/hr, u=initial velocity i.e 36 km/hr. we will change the v and u to m/s i.e 72X5/18=20 m/s and 36X5/18=10 m/s.

= mv - mu

= 1500X20 -  1500X10

=1500[ 20 - 10 ]

= 1500 X 10

= 15000 kg m/s
